What is Customs Clearance?

April 14, 2025

For many people, the term ‘customs’ is linked to some checks that are done when you travel abroad, but for those of us involved with the import and export of goods, customs clearance is a very specific process that is always present and needs to be addressed correctly.

In this article, we will find out what customs clearance means, what the customs clearance process is, what documentation is required, how long it can take, and how we can help. 

 

What does customs clearance mean?

Customs clearance is the process of taking goods through a country’s customs authority, either to import (bring in) or export (take out) the items in a legal manner. 

To get goods through customs, various export and import documents will need to be filled in correctly.

 

The customs clearance process:

Whilst customs clearance processes in each country can vary, the basic outline is similar:

 

  1. Goods arrive at the customs clearance area, for example, a port.
  2. The accompanying documentation is checked to ensure it is valid and complete.
  3. The goods are inspected to ensure they match the documentation.
  4. Relevant duties, tariffs, taxes, and any costs are calculated and paid.
  5. The goods can then leave the customs clearance area for their onward journey.

 

Issues arising in any one of these five steps can cause considerable delay and cost. This is one of the reasons that ensuring the correct documentation is fully completed is vital.

 

What documents are required for customs clearance?

For both import and export, the documents required are likely to include: a purchase order from the buyer, a sales invoice, a certificate of origin, a packing list, and details of the shipping route to date

Certain goods require specific import and export licences, in which case proof of these will need to be included. 

Knowing the exact documentation requirements for different classes of goods in different geographies is one of the services that a logistics partner can offer.

How long does customs clearance take?

A typical customs clearance might only take a matter of minutes or a few hours, but this can extend into days and weeks if there is missing documentation, or if a more detailed inspection of the goods is required. 

If documents are missing or a detailed inspection is required, the goods will be held for as long as deemed necessary by the clearance authority. It is for this reason that many companies choose to use a logistics partner with significant customs clearance experience.

 

Do customs check every package?

The widespread use of X-ray scanning, sniffer dogs, and random checking means that all goods will at least attract some scrutiny. Poor or damaged packaging or incomplete paperwork may attract more thorough checks, which may lead to longer clearance times. 

Just because lower-value goods might not attract a tariff or duty does not mean they will not be inspected.
